DAVID E. TINGLEY, OF MARSHALL, ILLINOIS CONCRETE-MOLD.

Application tiled November 12, 190?. Serial No. 527,795.

To all whom it may concern:

Be it known that I. l). .vm Tixonei', a citizen of the United States, residing at Marshall, in the county of Clark and State of Illinois. have invented certain new and use ful lmprm'cments in Concrete- Molds, of

which the following is a specification.

My invention relates to certain new and useitul nuprovenn-nts in concrete molds and has particular retercnce to molds tor hollow concrete masonry constructions for build-.

ing arches. conduits, sewers and other structures of this general class.

The particular object of my in ention is to improve certain details of coustructitm the form of mold disclosed in my Patent No. 931,351, granted August 1?, 1909.

A further object of my invention is to provide a means whereby the end wings and similar structures used for finishing the ends of culverts, sewers, etc.. can be molded as an integral part of the body of the structure.

\Vith these and other objects in view my invention consists in certain coustri'ntions, combinations and arrangements of parts the preferred form of which will be first described in connection with the accompanying drawings and then the invention particularly pointed out in the appended claims.

Figure 1 is a cross section of asewer pipe in process of construction in which my improved mold is employed; Fig. 2 is a detailed view of the improved form of connection between the two sections; Fig. 3 is a perspective view of said connecting parts with the parts shown in separated relation; Fig. 4 is a side view of said connecting parts showing the means for driving them into position to be locked in place; Fig. 5 is a perspective view of said means for drawing the connecting parts into proper position; Fig. (3 is a sectional view of a modification showing my invention, as adapted for arch work and the devices for holding wings on the end of such arch and Fig. 7 is a longitudinal section taken on line 7, 7 of Fig. 6.

In my prior patent above referred in I employ a plurality of sections which are r and 1-!.

adapted to he placed end to end to form the continuous construction, the. length of these sections depending upon the character of work to he done. Each of these mold sections is formed of a plurality of members 1 T. 8, EL 10 and i1, hinged together at 12, 13 While I have shown tour ofthese mend in the form of construction shown Specification of Letters Patent. Patented D131. 28, 1911.

i in Fig. 1, it is to he understood that this number may be increased or diminished as may be found desirable.

For conveniencein describing the form of member 8 as the top mcruber, the member 10 as the bottom member and the members 9 and 11 the side members. It is obvious that the relative position of these members may be changed as desired. The side membeis l) 4 and it are preferably formed with a plurality of curved T bars 15 as forminga r gid shell. The T'bars are formed in the are of a circle whose center is the longitudinal axis of the set up mold sections, and in the form 2 f my invention shown the plates 16 are riveted to these T bars though other form of cov ring may be used. and such covering need not of necessity be secured to the bars. The bottom section 10 is similarly formed of T bars 15 which are similarly covered by tom section, and preferably located between the T bars. I provide one or more U-shaped sections 17, in' which are journaicd the rolls 1B.

The construction so far described is the same as that; illustrated in my patent, ahove referred to. The upper section 8 of the pres ent construction is, however, formed in two parts 19 and 20, the part 19 being hinged to the section9 by the hinge 12, and the part 20 being hinged to the section 11 by the hinge 21. The curved bars 22 of those sections are also formed of T-shaped irons, said bars being of a length to overlap, as best l shown in Figs. 2 and 3. From these figures it will be seen thatone of the projecting sides of the T for the overlapped part of the bar is cut away, forming a pair of oppositely positioned notches which when locked together, will cause the parts. I.) and 20 of the member 8 to form a continuous struc ture. The sheathing plates 16 of these sections are beveled on their edges so as to form a tight joint.

In order to lock the bars 22 together :I provide the overlapped portion of said bars with openings 23 which register when the bars are in locked position, and which may be held together by pins 524 being passed through the openings. In order to prevent loss I preferably secure the pins to the bars adjacent the openings by means of flexibl securing devices 25.

In order to force the two parts of the secmy invention illustrated I will designate the nov ioo

tion 8 into position where the overlapping bars will have their openings 2-3 in registry, I provide a tool shown in detail in Fig. 5. This tool comprises ahandlc 26, having a pair of projecting jaws 27, 28, said jaws being spaced apart and projecting from the opposite sides of the handle, the jaw 27 being longer than the jaw 28. The jaw 27 carries near its outer end an inwardly project-ing pin 29, while the jaw 28 is provided. with an opening near its outer end through which may be passed a pin 31. The portions of the T bars 22 which are adapted to overlap are provided with openings 32 into which the pins 29 and 30 may be inserted when, by movement of the handlefltl, the overlapped portions of the bars may be brought into position to cause the registering of the openings 23 and held there while the pins .Z-l are passed through the openings. After this has been done the pin 31 in the handle can be withdrawn and then the handle removed.

As the greatest strain on the mold sections occurs when the concrete'is being placed in position around thc sections I preferably provide, as in my prior patent referred to, turn buckles 33 having hooked ends 34: adapted to engage openings formed in the-T irons of the various sections, whereby while the concrete is being placed in position around the sections they will be interiorly I braced. As soon as all the concrete is in place the turn buckles may be removed.

In Figs. 6 and 7 I have shown aconstruction adapted for building concrete arches, culverts and the like and which comprises a bottom member 35 which is flat, and two side niembers 36 and 37, the two side members being hinged to the bottom member at 38 and 39, and the two side members 36 and 37 being secured together by the latching means heretofore described and which I have only generally indicated in these figures. In this modification I havealso shown a modified form of interior bracing, which comprises a pair of bars 40, each formed by securing together two T irons, as best shown in Fi 7, whereby posts having four projecting flanges are provided. 41 are the lateral braces which are pinned to the flanges of the post 40 at their inner ends and also pinned to the projecting flanges of the curved T bars 15 of-the side sections. 42 are cross bars pinnedto the flanges of the upright post to hold the same 'properly spaced apart. The yertical posts at their upper and lower ends are also pinned to the projecting flanges of the curved bars 15.

In ordel: to tie the supports together I provide longitudinal fastening 43 which are provided at each end with U shaped yokes 44 adapted'to embrace projecting flanges of the post and which can also be readily pinned to said flanges. In Figs. Sand 7 I 'tion when expanded, a pair of strips longer ca ly also show means for forming a mold to provide wing sections on the ends of culverts, sewers and the like, and in the form shown comprisesa pair of uprights 45 adapted to hold a series of planks 46 against the end of a mold section, the uprights 45 be held in position by means of bolts 47 passing 'through the flanges of the post d0, the bolts being provided on their'exterior with nuts do. The bars iii are adapt d to extend above the top of the mold sections; as to support the planks 45 above the top of said section, m order to form a wing extending above the top of the culvert or sewer. Preferably these planks are provided with tongues and grooves in order that they may be interlocked in' position.

In order to form the inner face of the wings I provide inclined strips 49 which are connected to the strips 45 by means of the bolts 50 at the top and bottom, the bolts being provided with the nuts 51 on the outside of the structure. These plates4=9 are idapted to secure in position planks 52, forming between said planks 52 and the planks 45 a. space in which the wings are molded.

As the operation of my construction is fully described in my patent referred to I will refer to said patent :For such descrip tion.

by Letters Patent is 1. A mold comprising a plurality of .embers shaped to conform to the concrete or other construction to be molded thereover, said members being hinged together where by they may be collapsed, one of said members being composed of two parts adapted to be separated to collapse the mold, each of said parts beingprovided withcurved T bars running transversely of said part, the projecting portion of one side of each of the T bars being cut away, whereby said T bars may be overlap ed so that their overlapping portions wi form a complete T bar, said overlapping portions being pro- 'vided with pin-receiving holes, and a tool having a handle portion, and a bifurcated portion comprising members of unequal length, adapted to take over the flanges of said over lapping portions to draw the same into position to bring the pin-receiving holes therein into registry.

2. A mold section comprising a plurality of members shaped to conform to concrete or other structure to be molded thereover,

said members being hinged together whereby they may be collapsed to pass through an adjacent mold section, a pair of uprights spaced apart and secured interiorly to the top and bottom members of said mold secthan said uprights and placed verti across the end of the expanded section, bolts for removably securing said strips to said i In testimony whereof I afiix my signature uprights, inclined strips extending on each i in presence of two witnesses.

side of the expanded mold section, bolts for securing said inclined stri s to said vertical strips, and planking supported by said vertical an-Ll' inclined strips to complete the mold for the wings of a conduit.
